escape-sdk 1.0.1

OSRS Bot Development SDK with game-native structure

Escape

A Python SDK for Old School RuneScape (OSRS) bot development that communicates with RuneLite via a high-performance bridge. The architecture mirrors the game's interface, making it intuitive for OSRS developers.

Requirements

• Python 3.12+
• Linux with inotify support (required for event system)
• RuneLite with Escape plugin running

Features

• Game-Native Structure: Directory layout mirrors OSRS client interface (tabs, interfaces, world)
• Event-Driven Architecture: Zero-CPU inotify-based event system for real-time game state
• Singleton Pattern: All modules are singletons with lazy initialization
• Type-Safe: Full type hints with IDE autocomplete support
• Auto-Generated Constants: ItemID, NpcID, ObjectID, InterfaceID, and more
• 3D Projection: Convert local/world coordinates to screen coordinates

Installation

# Clone the repository
git clone https://github.com/escape/escape.git
cd escape

# Install with development dependencies
pip install -e ".[dev]"

# Install pre-commit hooks
pre-commit install

Quick Start

from escape.client import client

# Client auto-connects on import and starts event consumer
# All modules are singletons - no instantiation needed

# Access inventory
items = client.tabs.inventory.getItems()
for item in items:
    print(f"{item.name}: {item.quantity}")

# Check player state
pos = client.player.position
print(f"Player at: {pos}")

# Use bank interface
if client.interfaces.bank.isOpen():
    client.interfaces.bank.depositAll()

# Direct module access (alternative pattern)
from escape.tabs.inventory import inventory
from escape.input.mouse import mouse

inventory.clickItem(995)  # Click coins
mouse.leftClick(100, 200)

Singleton Pattern

All modules use the singleton pattern with __new__ + _init():

# Two equivalent access patterns:

# Via client namespace
from escape.client import client
client.tabs.inventory.getItems()

# Direct import
from escape.tabs.inventory import inventory
inventory.getItems()

Event System

The SDK uses an inotify-based event system for zero-CPU-usage when idle:

from escape.client import client

# Access cached game state (updated automatically)
tick = client.cache.tick
energy = client.cache.energy
position = client.cache.position

# Get recent events
chats = client.cache.getRecentEvents('chat_message', n=10)
stats = client.cache.getRecentEvents('stat_changed', n=5)

# Access varps/varbits
quest_points = client.cache.getVarp(101)

# Check data freshness
if client.cache.isFresh(max_age=1.0):
    print(f"Data age: {client.cache.getAge():.2f}s")

Event Channels:

Channel Type	Channels	Description
Ring Buffer	varbit_changed, chat_message, item_container_changed, stat_changed, animation_changed	Guaranteed delivery, keeps history
Latest State	gametick, camera_changed, world_view_loaded, world_entity, menu_open, ground_items	Current state only

Projection System

Convert local/world coordinates to screen coordinates:

from escape.world.projection import projection

# Auto-configured from events - just use it
screen_pos = projection.localToCanvasSingle(localX, localY, plane)
if screen_pos:
    screenX, screenY = screen_pos
    print(f"Screen position: ({screenX}, {screenY})")

# Batch projection
import numpy as np
xs = np.array([1000, 2000, 3000])
ys = np.array([1000, 2000, 3000])
screenX, screenY, valid = projection.localToCanvas(xs, ys, plane=0)

Query Builder

Direct RuneLite API access with fluent interface:

from escape.client import client

# Build and execute queries
q = client.query()
result = q.execute({
    "inventory": q.client.getItemContainer(93),
    "position": q.localPlayer.getWorldLocation(),
    "health": q.localPlayer.getHealthRatio()
})

    def __init__(self, client=None):
        self.client = client or getClient()
